With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new jig device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 8, the mortise jig assembly 10 generally comprises a block 12 that is longitudinally elongated. The block 12 has a first set of mortises 14, a second set of mortises 16, a third set of mortises 18 and a fourth set of mortises 20. Each of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 and the fourth set of mortises 20 has a unique offset distance with respect to each other. The block 12 is clamped to a face 22 of a door 24 having the block 12 being aligned with an edge 26 of the door 24. Moreover, the block 12 is positioned such that a selected one of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20 is aligned with the face 22 of the door 24. The door 24 may be an interior door or an exterior door that is being prepared for installation in a doorway of a house or other similar building.

The block 12 has a first end 28, a second end 30 and an outer surface 32 extending therebetween, and the outer surface 32 has a first side 34, a second side 36, a third side 38 and a fourth side 40. Additionally, the block 12 is elongated between the first end 28 and the second end 30. The first side 34 is oriented at a right angle with respect to the second side 36, and the second side 36 is oriented at a right angle with respect to the third side 38. Moreover, the third side 38 is oriented at a right angle with respect to the fourth side 40 and the fourth side 40 is oriented at a right angle with respect to the first side 34. The first set of mortises 14 is recessed into the first side 34, the second set of mortises 16 is recessed into the second side 36, the third set of mortises 18 is recessed into the third side 38, and the fourth set of mortises 20 is recessed into the fourth side 40.

Each of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 and the fourth set of mortises 20 extends between the first end 28 and the second end 30 of the block 12. Additionally, each of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 and the fourth set of mortises 20 including a reference mortise 42. The reference mortise 42 of the first set of mortises 14 is oriented flush with an intersection between the first side 34 and the fourth side 40 of the outer surface 32. The reference mortise 42 of the second set of mortises 16 is offset 1/32 inch from an intersection between the second side 36 and the first side 34. The reference mortise 42 of the third set of mortises 18 is offset 1/16 inch from an intersection between the third side 38 and the second side 36. Finally, the reference mortise 42 of the fourth set of mortises 20 is offset 3/32 inch from an intersection between the third side 38 and the fourth side 40.

Each of the first set of mortises 14 is spaced apart ⅛ inch from each other, and each of the second set of mortises 16 is spaced apart ⅛ inch from each other. Each of the third set of mortises 18 is spaced apart ⅛ inch from each other, and each of the fourth set of mortises 20 is spaced apart ⅛ from each other. The block 12 has a pair of first holes 44 each extending through the first side 34 and the third side 38. The block 12 has a pair of second holes 46 each extending through the second side 36 and the fourth side 40. Additionally, each of the second holes 46 interests a respective one of the first holes 44.

A jig panel 48 is provided that has a plurality of jig mortises 50 recessed therein. The jig panel 48 is positionable against the edge 26 of the door 24 having the jig mortises 50 engaging respective ones of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20 in the block 12. In this way the jig panel 48 is retained at a selected location on the edge of the door 24. The jig panel 48 has a guide hole 52 therein thereby facilitating the guide hole 52 to be aligned with a preferred location to cut a hinge recess 54 in the edge 26 of the door 24. In this way the block 12 and the jig panel 48 facilitate the hinge recess 54 to be precisely located on the edge of the door 24.

The jig panel 48 has a bottom surface 56, a top surface 58 and a perimeter edge 60 extending therebetween, and the perimeter edge 60 has a front side 62, a back side 64, a first lateral side 66 and a second lateral side 68. The plurality of jig mortises 50 is recessed into the bottom surface 56 of the jig panel 48 and each of the jig mortises 50 extends between the first lateral side 66 and the second lateral side 68. Moreover, the jig mortises 50 are spaced apart from each other and are distributed between the front side 62 and the back side 64. Each of the jig mortises 50 is spaced ⅛ inch apart from each other thereby facilitating each of the jig mortises 50 to engage either the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20.

The guide hole 52 extends through the top surface 58 and the bottom surface 56 of the jig panel 48, and the guide hole 52 is centrally positioned on the jig panel 48. The guide hole 52 has a bounding edge 69 and the bounding edge 69 has a plurality of intersecting sides 70 such that the guide hole 52 has a rectangular shape. The guide hole 52 is spaced from the face 22 of the door 24 a distance corresponding to the offset of either the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20. The jig panel 48 has a pair of slots 71 each extending through the top surface 58 and the bottom surface 56. Each of the slots 71 extends substantially between the front side 62 and the back side 64 of the perimeter edge 60 of the jig panel 48. Each of the slots 71 is positioned between the guide hole 52 and a respective one of the first lateral side 66 and the second lateral side 68. Moreover, each of the slots 71 is aligned with a respective one of the first holes 44 or the second holes 46 when the jig panel 48 is positioned on the block 12.

The top surface 58 has a pair of channels 72 each extending toward the bottom surface 56 of the jig panel 48, and each of the channels 72 extends between the front side 62 and the back side 64. Each of the channels 72 is aligned with a respective one of the slots 71 and each of the channels 72 is oriented collinear with the respective slot 64. A pair of bolts 73 is provided and each of the bolts 73 is extendable through the jig panel 48 and the block 12 for attaching the jig panel 48 to the block 12. Each of the bolts 73 is extendable through a respective one of the slots 71 having the bolts 73 extending fully through the respective first hole 44 or the respective second hole 46 in the block 12 that is aligned with the respective slot 64. Each of the channels 72 in the jig panel 48 accommodates a head 74 of the bolts 73 when the bolts 73 are extended through the respective slot 64 thereby facilitating the head 74 of each of the bolts 73 to be spaced downwardly from the top surface 58 of the jig panel 48. A pair of nuts 76 is each threadable onto a respective one of the bolts 73 when the bolts 73 are extended through the jig panel 48 and the block 12 for retaining the block 12 on the jig panel 48. In an alternative embodiment 78 as is most clearly shown in FIG. 7, the jig panel 48 may have a pair of guide holes 80 extending therethrough and each of the guide holes 80 may have a unique perimeter with respect to each other.

In use, the block 12 is clamped on the face 22 of the door 24 such that a selected one of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20 is aligned with the edge 26 of the door 24. The jig panel 48 is positioned against the edge of the door 24 such that the jig mortises 50 engage the block 12. Each of the bolts 73 is extended through the slots 71 to engage the respective first holes 44 or second holes 46 in the block 12 and the nuts 76 are threaded onto the bolts 73 to retain the jig panel 48 on the block 12. In this way the guide hole 52 is precisely located on the edge of the door 24. Thus, a router or other type of tool can be employed to carve out the hinge recess 54 in the guide hole 52, thereby precisely locating the hinge recess 54.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
